BACKGROUND 1. Field of the Disclosure

The present disclosure relates generally to electronic devices, and more particularly, to electronic devices having an antenna.

2. Description of the Related Art

The term “electronic device” indicates a device for performing a particular function according to programs equipped on the device. For example, electronic devices may output stored information as voices or images. Portable electronic devices, such as laptop computers, tablet personal computers (PCs), electronic schedulers, portable multimedia players, and mobile terminals, usually have a display and a battery.

Mobile communication terminals and wearable devices have become more compact and lightweight while consistently gaining new functionalities, thereby satisfying customer demands.

Recent electronic devices contain user authentication information enabling use for online/offline payments. For example, a user may use his or her electronic device containing credit card information instead of their credit card. An electronic device with such credit card functionality may perform payment in a near field communication (NFC) or magnetic secure transmission (MST) scheme.

An electronic device having an antenna for NFC purposes may deliver credit card information to a reader for payment. However, conventional antennas for these electronic devices emit radio signals in a direction perpendicular to the display, which inconveniently requires the user to angle the display towards the reader for payment.

As such, there is a need in the art for an antenna that does not require such user manipulation in order to process the payment in the electronic device.

The first antenna 103 may emit the other M2 of the radio signals through the space 134 to the outside of the housing 101 through the display 102 and the front cover 111. The combination of the other M2 of the radio signals, in addition to the radio signal M1, enhances the overall emission capability.

FIG. 8 is a plan view illustrating radio signals from an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 8, a first antenna in an electronic device 100 may generate radio signals M1 and M2 at side surfaces of the electronic device 100. For example, a first reader I1 that is disposed at a first side surface of the electronic device 100 may receive the radio signals M1 and M2, generating a current F1. A second reader I2 disposed at a second surface of the electronic device 100 may receive the radio signals M1 and M2, generating a current F2. Conventional antennas emit radio signals in a direction perpendicular to the display. Thus, readers disposed at side surfaces of the electronic device may have difficulty receiving the radio signals.

According to an embodiment of the present disclosure, the first antenna in the electronic device 100 may generate radio signals at a side surface of the electronic device 100, in contrast with the conventional antennas, thereby improving the overall emission capability of the antenna.

The electronic device may further include a housing, a circuit board disposed inside the housing and having the second antenna mounted thereon, and an wearing part coupled to the housing and having a longitudinal direction and put on a user's wrist, wherein the second antenna, as viewed from a front surface of the housing, may be positioned away from a center of the housing within an acute angle range with respect to the wearing part.

The second antenna may be disposed adjacent to an edge of the circuit board.

A magnetic body of the second antenna may be parallel with a longitudinal direction of the wearing part.

A magnetic body of the second antenna may be formed of ferrite.

An angle in the acute angle range may be 0 degrees to 30 degrees.

An angle in the acute angle range, as viewed from the front surface of the housing, may be 0 degrees to 30 degrees when measured to a left of the wearing part on the center of the housing.

The front surface of the housing may be implemented to include an analog watch, and the second antenna may be at an 11 o'clock position to a 12 o'clock position of the analog watch as viewed from the front surface of the housing.

As is apparent from the foregoing description, according to an embodiment of the present disclosure, the first antenna in the electronic device is provided between the display and the battery, and the conducting wire-wound magnetic body is disposed parallel with a surface of the display. Thus, a radio signal emitted from the first antenna may travel around the display and the battery to the outside of the electronic device. For example, the radio signal emitted from the first antenna does not receive interference by the display, thereby enhancing emission capability.

According to an embodiment of the present disclosure, the first conducting wire in the electronic device is spaced apart from the second conducting wire while forming the space, leading to an enhanced emission capability for the electronic device.

While the present disclosure has been shown and described with reference to embodiments thereof, it will be apparent to those of ordinary skill in the art that various changes in form and detail may be made thereto without departing from the spirit and scope of the present disclosure as defined by the appended claims.
